Chen Jining, deputy secretary of the Beijing Municipal Party committee and mayor, Wang Zhijun, member of the Party group and vice minister of the Ministry of industry and information technology, Peng Huagang, member of the Party committee and Secretary General of the state owned assets supervision and Administration Commission of the State Council, and he Defang, deputy Secretary General of the Ministry of science and technology, attended the meeting and delivered a speech.
        Jin Wei, vice mayor of Beijing and Secretary General of the municipal government, presided over the meeting. Liu Yinchun, Deputy Secretary General of Beijing municipal government, Zheng Zhiming, academician of Chinese Academy of Sciences and professor of Beijing University of Aeronautics and Astronautics, Zheng Weimin, academician of Chinese Academy of engineering and professor of Tsinghua University, etc. attended the promotion meeting. At the promotion meeting, Xu Qiang, Secretary of the Party group of the Municipal Science and Technology Commission, Zhongguancun Management Committee and director of the Municipal Science and Technology Commission, introduced the establishment of the Chang'an chain ecological alliance; Dong Jin, President of Beijing micro chip blockchain and edge computing research institute, released the blockchain software and hardware technology system "chainmaker"; Tian Guoli, Secretary of the Party committee and chairman of China Construction Bank Corporation, released the scenario of supply chain financial ecological network; Xin Baoan, chairman of the State Grid Corporation of China and Secretary of the Party group, released the carbon trading ecological network scenario.
        At the meeting, 27 member units of the alliance jointly signed a proposal to jointly build the Chang'an chain ecological alliance. "Chang'an chain" is characterized by independent control, flexible assembly, integration of hardware and software, and open source. It is jointly developed by Beijing micro chip research institute, Tsinghua University, Beijing University of Aeronautics and Astronautics, Tencent, Baidu and other well-known universities and enterprises. It is named "Chang'an chain", which means "long-term stability, create brilliance and link the world". "Chang'an chain" adheres to independent research and development, adheres to the concept of open source, open construction and sharing, and aims to meet the technical needs of the next generation of blockchain, such as large-scale node networking, high transaction processing performance, strong data security and privacy. It integrates the special acceleration chip hardware of blockchain and the bottom software platform that can be assembled to provide a new solution for building a high-performance, reliable and secure digital infrastructure.
        In terms of software, the "Chang'an chain" has created a deep modular, assembleable and high-performance block chain underlying technology architecture. It has realized the independent research and development of more than ten core modules such as anti quantum encryption algorithm, manageable pipeline consensus and hybrid segmented storage. The transaction processing capacity has reached 100000 TPS, ranking the world's leading level. The "Chang'an chain" software platform can automatically select and assemble appropriate components according to different business scenarios to meet different needs such as asset transactions, data sharing, and trusted certificates. In terms of hardware, it is the world's first 96 core blockchain chip architecture based on risc-v open source instruction set to build an efficient and reliable operating environment with physical security isolation, realize parallel and accelerated processing of smart contracts, and greatly improve the trading performance of large-scale blockchain networks.
        In the release of the first batch of key application scenarios of the alliance, Tian Guoli, chairman of China Construction Bank, released the supply chain finance application scenario and created a commercial bank financial service platform based on "Chang'an chain", serving more than 100 urban commercial banks, more than 1000 rural commercial banks and more than 10 million enterprises.
